    dct:description """A topographic lidar survey was conducted from September 5 to October 11, 2012, for the barrier islands of Alabama, Mississippi and southeast Louisiana, including the coast near Port Fourchon.  Most of the data were collected September 5-10, 2012, with a reflight conducted on October 11, 2012, to increase point density in some areas.
The data were collected at a nominal pulse space of 1-meter (m) and processed to identify bare earth elevations.
Bare earth Digital Elevation Models(DEMs) were generated based on these data.
Aero-Metric, Inc., was contracted by the U.S. Geological Survey (USGS) to collect and process the lidar data.
The bare earth DEMs are 32-bit floating point ERDAS Imagine (IMG) files with a horizontal spatial resolution of 1-m by 1-m. They are projected to UTM zone 15N or 16N NAD83 meters. Their vertical datum is NAVD88 (GEOID12) meters.
The DEMs are organized on a 2-kilometer (km) by 2-km tiling scheme that covers the entire survey area.
These lidar data are available to Federal, State and local governments, emergency-response officials, resource managers, and the general public.""" ;
